Ali, a nine-tailed fox from Qingqiu, sneaked into the world of immortality in search of life-extending celestial herbs, accidentally broke into the Qinghan Palace of the ascetic immortal Mo Yuan, and was forced to stay as a medical apprentice. She hid herself as a fox to avoid being chased, but she fell in love with Mo Yuan during the healing process. Mo Yuan's dusty memory actually contained a life and death contract with her in her previous life. Immortals and demons have different paths, and the demon world is chasing them. The two must work together to break the shackles of heaven.
